Teenager allegedly killed 15-year-old at pajama party after walking nearly 6 miles to victim’s home

A teenager from Florida was accused of murder, among other things, for stabbing a 15-year-old boy to death while hosting a pajama party. The boy was killed in the process.

Connor Michael Gill, who turned 15 less than a month ago, was killed in a stabbing attack at his home in Wildwood, Florida, by a 16-year-old boy on Saturday, June 1, the Sumter County Sheriff’s Office said in a statement. (PEOPLE is not identifying the suspect because of his age.)

Police responded to a report of an assault Saturday night and found Connor and an adult victim with stab wounds, the statement said.

The victims were flown by helicopter to local hospitals and Connor’s death was pronounced at 1 a.m. the next morning.

Authorities allege the suspect knew the victim and showed up at the pajama party “unannounced,” “banging” on the door and stabbing him when Connor opened the door.

“This was without a doubt a deliberate and targeted attack,” Pat Breeden of the Sheriff’s Department said in a follow-up statement on Sunday.

Breeden said the suspect allegedly told authorities he ordered two guns online a few days before the attack and that after receiving them on Saturday, he “unpacked them, played with them a bit” and then walked nearly six miles to Connor’s house.

The suspect “banged on the door, forced his way in, stabbed the two victims and then fled the house,” Breeden claimed in his statement.

Police said they located the suspect using a helicopter and that he had the suspected murder weapons with him at the time.

Michael Carr, a family friend who witnessed the attack, told FOX 35 that the suspect “had a mission in mind.”

“It was cold. That was not normal for a 16-year-old boy,” Carr said. “He didn’t look right.”

The adult victim, a 48-year-old man, survived the attack.

According to Carr, the suspect stabbed the adult, then “turned around, walked out the door and said, ‘Everyone on guard.'”

Carr said Connor was a “cool” kid and a “typical 15-year-old.”

“I mean, he liked to have fun and he was fun to be around and he liked video games,” Carr told the outlet. “He had goals.”

Police did not give a motive for the murder. Both Connor and the suspect were former students of the same school, but were being home-schooled at the time of Connor’s murder, according to police.

The suspect is charged with first-degree murder, aggravated assault with a deadly weapon without intent to kill and armed burglary, police said. It was not immediately clear whether he pleaded guilty or had hired an attorney to speak on his behalf.
